Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Evaluates unit test results' gives no information about whether this is a read-only operation, whether it modifies data, what permissions might be required, what the typical response format looks like, or any rate limits or side effects. For a tool with no annotation coverage, this description is completely inadequate for understanding its behavioral characteristics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
